The interim consolidated financial statements included herein as of September 30, 2020 and for the three and nine months ended September 30, 2020 and 2019 have been prepared by the Company, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission, and therefore, do not include all information or footnotes necessary for a complete presentation of the consolidated statements of financial condition, results of operations and cash flows in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The consolidated statement of financial condition at December 31, 2019 has been derived from the audited consolidated financial statements at that date, but does not include all of the information and footnotes required by GAAP for complete consolidated financial statements. The consolidated financial statements reflect all adjustments that are, in the opinion of management, necessary for a fair statement of such information and to make the financial statements not misleading. These interim consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. The consolidated statements of income for the three and nine months ended September 30, 2020 are not necessarily indicative of the results for any subsequent period or the entire year ending December 31, 2020.  To prepare these consolidated financial statements in conformity with GAAP, management of the Company made a number of estimates and assumptions relating to the reporting of assets and liabilities and the reporting of revenue and expenses. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, securities valuation estimates, evaluation of impairment of securities and income taxes.  The Company has evaluated events and transactions occurring subsequent to the statement of financial condition as of September 30, 2020 for items that should potentially be recognized or disclosed in these consolidated financial statements. The evaluation was conducted through the date these consolidated financial statements were issued.

New Accounting Standards [Abstract]
New Accounting Standards	Note 2 – New Accounting Standards  Impact of Adoption of Recent Accounting Standards and Accounting Guidance  Under Section 4013 of the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”), which was signed into law on March 27, 2020, financial institutions have the option to temporarily suspend certain requirements under U.S. generally accepted accounting principles related to troubled debt restructurings (“TDRs”) for a limited period of time to account for the effects of COVID-19. This provision allows a financial institution the option to not apply the guidance on accounting for TDRs to loan modifications, such as extensions or deferrals, related to COVID-19 made between March 1, 2020 and the earlier of (i) December 31, 2020 or (ii) 60 days after the end of the COVID-19 national emergency. The relief can only be applied to modifications for borrowers that were not more than 30 days past due as of December 31, 2019. The Company elected to adopt this provision of the CARES Act.  In addition, the Company’s banking regulators and other financial regulators, on March 22, 2020 and revised April 7, 2020, issued a joint interagency statement titled the “Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus” that encourages financial institutions to work prudently with borrowers who are or may be unable to meet their contractual payment obligations due to the effects of the COVID-19 pandemic. Pursuant to the interagency statement, loan modifications that do not meet the conditions of Section 4013 of the CARES Act may still qualify as a modification that does not need to be accounted for as a TDR. Specifically, the agencies confirmed with the staff of the Financial Accounting Standards Board (“FASB”) that short-term modifications made in good faith in response to the pandemic to borrowers who were current prior to any relief are not TDRs under GAAP. This includes short-term (e.g. six months) modifications such as payment deferrals, fee waivers, extensions of repayment terms, or delays in payment that are insignificant. Borrowers considered current are those that are less than 30 days past due on their contractual payments at the time a modification program is implemented. Appropriate allowances for loan and lease losses are expected to be maintained. With regard to loans not otherwise reportable as past due, financial institutions are not expected to designate loans with deferrals granted due to the pandemic as past due because of the deferral. The interagency statement also states that during short-term pandemic-related loan modifications, these loans generally should not be reported as nonaccrual. The Company elected to adopt this interagency guidance.  The Company implemented a loan modification program for impacted customers, in line with regulatory guidance, allowing customers to defer loan payments. The majority of loan deferrals were granted for deferral of principal and interest payments for 90 days, and up to 180 days in some instances, with the loan repayment period extended by the deferral period. The requests are evaluated individually and approved modifications are based on the unique circumstances of each borrower. During the second quarter of 2020, the Company approved loan payment deferral requests of up to 90 days on 219 loans, representing $103.1 million, or 21.1% , of the Bank’s loan portfolio as of June 30, 2020. 88.2% of the loan balances with payment deferrals were for commercial real estate loans and commercial business loans, while the remaining 11.8% were for residential mortgage, home equity and consumer loans. The number of loan payment deferral requests has decreased and as of October 31, 2020 , there were 25 loans, representing $20.8 million, or 4.1% of the Bank’s loan portfolio, that are deferring payments, as follows:     Loan Type Number of Loans Balance Outstanding Weighted Average Interest Rate   Commercial real estate 16 $ 17,608 5.06 %  Commercial business 9 3,165 5.02  25 $ 20,773 5.05 % These loans were current at the time of modification and were not considered troubled debt restructurings based on the CARES Act and interagency guidance noted above and we have not accounted for the loans as TDRs, nor have we designated the loans as past due or non-accrual.  The adoption of these provisions under Section 4013 of the CARES Act and interagency guidance may have a material impact on the Company’s consolidated financial statements; however, the Company cannot quantify the impact at this time.  Accounting Standards to be Adopted  In June 2016, the FASB issued Accounting Standard Update (“ASU”) 2016-13, “ Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ” (“ASU 2016-13”). ASU 2016-13 requires credit losses on most financial assets measured at amortized cost and certain other instruments to be measured using an expected credit loss model (referred to as the current expected credit loss (“CECL”) model). Under the CECL model entities will estimate credit losses over the entire contractual term of the instrument (considering estimated prepayments, but not expected extensions or modifications unless reasonable expectation of a troubled debt restructuring exists) from the date of initial recognition of that instrument. Further, ASU 2016-13 made certain targeted amendments to the existing impairment standards for available for sale (“AFS”) debt securities. For an AFS debt security for which there is neither the intent nor a more-likely-than-not requirement to sell, an entity will record credit losses as an allowance rather than a write-down of the amortized cost basis. An entity will apply the amendments in ASU 2016-13 through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective.  The Company has determined its data requirements and is developing its methodologies for calculating the expected credit losses under ASU 2016-13 which has allowed the Company to run parallel loss reserve calculations. Data integrity associated with these methodologies is being reviewed and enhancements to the current process are being considered. We expect that the new guidance will result in an increase to the allowance for loan losses given that the allowance will be required to cover the full remaining expected life of the portfolio, rather than the incurred loss under the current accounting standard. The extent of this increase is still being evaluated. We are also reviewing the impact of additional disclosures required under ASU 2016-13 on our ongoing financial reporting procedures.  ASU 2016-13 was originally effective for the Company in 2020. In November 2019, the FASB issued guidance to defer the effective date for smaller reporting companies such as the Company until January 1, 2023.

At September 30, 2020, thirty-two municipal bonds with a cost of $10.7 million and fair value of $11.2 million were pledged under a collateral agreement with the Federal Reserve Bank (“FRB”) of New York for liquidity borrowing. At December 31, 2019, thirty-three municipal bonds with a cost of $10.9 million and fair value of $11.2 million were pledged with the FRB. In addition, at September 30, 2020 seventeen municipal bonds with a cost of $3.9 million and fair value of $4.1 million were pledged as collateral for customer deposits in excess of the Federal Deposit Insurance Corporation (“FDIC”) insurance limits. At December 31, 2019, sixteen municipal bonds with a cost of $3.6 million and fair value of $3.7 million were pledged as collateral for customer deposits in excess of the FDIC insurance limits.

At September 30, 2020, the Company’s investment portfolio included fourteen securities in the “unrealized losses less than twelve months ” category and five securities in the “unrealized losses twelve months or more” category. Management has the intent and ability to hold these securities until maturity. Management believes the temporary impairments were due to declines in fair value resulting from changes in interest rates and/or increased credit liquidity spreads since the securities were purchased. The unrealized losses on debt securities shown in the previous tables were recorded as a component of other comprehensive income, net of tax expense on the Company’s consolidated statements of stockholders’ equity.  The following table presents a summary of the credit-related OTTI charges recognized as components of income:   For the Nine Months Ended September 30,  2020 2019  (Dollars in thousands)  Beginning balance $ 294 $ 347  Additions:  Credit loss not previously recognized - -  Reductions:  Losses realized during the period on OTTI previously recognized - -  Receipt of cash flows on previously recorded OTTI (48) (39)  Ending balance $ 246 $ 308  A deterioration in credit quality and/or other factors that may limit the liquidity of a security in our portfolio might adversely affect the fair values of the Company’s investment portfolio and may increase the potential that certain unrealized losses will be designated as “other-than-temporary” and that the Company may incur additional write-downs in future periods.  During the nine months ended September 30, 2020 and 2019, the Company did no t sell any available for sale debt securities.

During the nine months ended September 30, 2020 and 2019, the Company recognized an unrealized loss of $24, 000 and an unrealized gain of $57,000 , respectively, on the equity securities. There were no sales of equity securities during the three and nine months ended September 30, 2020 and 2019.

Allowance for Loan Losses

Allowance for Loan Losses [Abstract]
Allowance for Loan Losses	Note 4 - Allowance for Loan Losses  Management segregates the loan portfolio into loan types and analyzes the risk level for each loan type when determining its allowance for loan losses. The loan types are as follows:  Real Estate Loans: · One- to Four-Family – are loans secured by first lien collateral on residential real estate primarily held in the Western New York region. These loans can be affected by economic conditions and the value of underlying properties. Western New York’s housing market has consistently demonstrated stability in home prices despite economic conditions. Furthermore, the Company has conservative underwriting standards and its residential lending policies and procedures ensure that its one- to four-family residential mortgage loans generally conform to secondary market guidelines. · Home Equity - are loans or lines of credit secured by first or second liens on owner-occupied residential real estate primarily held in the Western New York region. These loans can also be affected by economic conditions and the values of underlying properties. Home equity loans may have increased risk of loss if the Company does not hold the first mortgage resulting in the Company being in a secondary position in the event of collateral liquidation. The Company does not originate interest only home equity loans. · Commercial Real Estate – are loans used to finance the purchase of real property, which generally consists of developed real estate that is held as first lien collateral for the loan. These loans are secured by real estate properties that are primarily held in the Western New York region. Commercial real estate lending involves additional risks compared with one- to four-family residential lending, because payments on loans secured by commercial real estate properties are often dependent on the successful operation or management of the properties, and/or the collateral value of the commercial real estate securing the loan, and repayment of such loans may be subject to adverse conditions in the real estate market or economic conditions to a greater extent than one- to four-family residential mortgage loans. Also, commercial real estate loans typically involve relatively large loan balances concentrated with single borrowers or groups of related borrowers. · Construction – are loans to finance the construction of either one- to four-family owner occupied homes or commercial real estate. At the end of the construction period, the loan automatically converts to either a one- to four-family or commercial mortgage, as applicable. Risk of loss on a construction loan depends largely upon the accuracy of the initial estimate of the value of the property at completion compared to the actual cost of construction. The Company limits its risk during construction as disbursements are not made until the required work for each advance has been completed and an updated lien search is performed. The completion of the construction progress is verified by a Company loan officer or inspections performed by an independent appraisal firm. Construction loans also expose us to the risk of construction delays which may impair the borrower’s ability to repay the loan.  Other Loans: · Commercial – includes business installment loans, lines of credit, and other commercial loans. Most of our commercial loans have fixed interest rates, and are for terms generally not in excess of 5 years. Whenever possible, we collateralize these loans with a lien on business assets and equipment and require the personal guarantees from principals of the borrower. Commercial loans generally involve a higher degree of credit risk, as commercial loans can involve relatively large loan balances to a single borrower or groups of related borrowers, with the repayment of such loans typically dependent on the successful operation of the commercial business and the income stream of the borrower. Such risks can be significantly affected by economic conditions. Although commercial loans may be collateralized by equipment or other business assets, the liquidation of collateral in the event of a borrower default may be an insufficient source of repayment because the equipment or other business assets may be obsolete or of limited use, among other things. Accordingly, the repayment of a commercial loan depends primarily on the credit worthiness of the borrowers (and any guarantors), while liquidation of collateral is a secondary and often insufficient source of repayment. · Consumer – consist of loans secured by collateral such as an automobile or a deposit account, unsecured loans and lines of credit. Consumer loans tend to have a higher credit risk due to the loans being either unsecured or secured by rapidly depreciable assets. Furthermore, consumer loan payments are dependent on the borrower’s continuing financial stability, and therefore are more likely to be adversely affected by job loss, divorce, illness or personal bankruptcy.  The allowance for loan losses is a valuation account that reflects the Company’s evaluation of the losses inherent in its loan portfolio. In order to determine the adequacy of the allowance for loan losses, the Company estimates losses by loan type using historical loss factors, as well as other environmental factors, such as trends in loan volume and loan type, loan concentrations, changes in the experience, ability and depth of the Company’s lending management, and national and local economic conditions. The Company's determination as to the classification of loans and the amount of loss allowances are subject to review by bank regulators, which can require the establishment of additional loss allowances.  The Company also reviews all loans on which the collectability of principal may not be reasonably assured, by reviewing payment status, financial conditions and estimated value of loan collateral. These loans are assigned an internal loan grade, and the Company assigns an amount of loss allowances to these classified loans based on loan grade.  Although the allocations noted below are by loan type, the allowance for loan losses is general in nature and is available to offset losses from any loan in the Company’s portfolio. The unallocated component of the allowance for loan losses reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for existing specific and general losses in the portfolio.  The projected economic impact of COVID-19 resulted in the Company recording an $828,000 provision to allowance for loan losses during the nine months ended September 30, 2020 to account for adjustments to certain qualitative factors that reflected the uncertain aspects of the pandemic on economic conditions and borrowers’ ability to repay the loans. A general review of all commercial real estate and commercial business loans that received an initial loan payment deferral as a result of the COVID-19 impact was performed. Refer to Note 2 – New Accounting Standards for information on the loan payment deferrals granted by the Bank. At this time management has not changed its classification of these loans due to the quality knowledge our loan officers have obtained from their discussions with the borrowers and due to the strength of the collateral and guarantors. Management continues to carefully monitor those borrowers who remain on payment deferral for additional signs of distress that would result in a downgrade in loan classification. The net provision for loan losses of $1.1 million during the nine months ended September 30, 2020 included a $297,000 provision related to additional adjustments which were made to account for, increases in classified loans, net loan charge-offs, changes in the historical loss factor, loan originations and payoffs and changes in the mix of the loan portfolio.  The Company is participating in the Small Business Administration (“SBA”) Paycheck Protection Program (“PPP”) under the CARES Act. The CARES Act authorized the SBA to guarantee loans under a new 7(a) loan program known as the PPP. As a qualified SBA lender, the Company was automatically authorized to originate PPP loans. The SBA will guarantee 100% of the PPP loans made to eligible borrowers. During the first nine months of 2020, the Bank originated 252 SBA PPP loans for our customers, which totaled $26.9 million. We funded $18.4 million of PPP loans directly with the remaining $8.5 million funded indirectly via our partnership with Pursuit, a SBA lender that operates in the northeast. At September 30, 2020, there were $18.6 million in PPP loans outstanding and recorded as commercial business loans. In accordance with the SBA terms and conditions on these PPP loans, the Company recorded approximately $247,000 in net fees associated with the processing of these loans. Upon funding the loans, the net fees were deferred and will be amortized over the life of the loans as an adjustment to yield. We are in the process of assisting borrowers who have received PPP loans with the forgiveness application phase of the program. As of September 30, 2020, we have not yet submitted any forgiveness applications with the SBA. It is expected that most customers will apply and receive PPP loan forgiveness during the next six months, upon which any unamortized deferred fees will be recognized as an adjustment to interest income .  The following tables summarize the activity in the allowance for loan losses for the three and nine months ended September 30, 2020 and 2019 and the distribution of the allowance for loan losses and loans receivable by loan portfolio class and impairment method as of September 30, 2020 and December 31, 2019:     Real Estate Loans Other Loans  One- to Four-Family (2) Home Equity Commercial Construction - Commercial Commercial Consumer Unallocated Total  (Dollars in thousands)  September 30, 2020  Allowance for Loan Losses:  Balance – July 1, 2020 $ 426 $ 169 $ 3,377 $ 554 $ 481 $ 34 $ 23 $ 5,064  Charge-offs - (6) - - - (17) - (23)  Recoveries - - - - - 6 - 6  Provision (credit) (23) - 67 6 179 1 70 300  Balance – September 30, 2020 $ 403 $ 163 $ 3,444 $ 560 $ 660 $ 24 $ 93 $ 5,347   Balance – January 1, 2020 $ 436 $ 129 $ 2,682 $ 388 $ 478 $ 26 $ 128 $ 4,267  Charge-offs (26) (6) - - (5) (27) - (64)  Recoveries - 1 1 - 4 13 - 19  Provision (credit) (7) 39 761 172 183 12 (35) 1,125  Balance – September 30, 2020 $ 403 $ 163 $ 3,444 $ 560 $ 660 $ 24 $ 93 $ 5,347  Ending balance: individually evaluated for impairment $ - $ - $ - $ - $ - $ - $ - $ -  Ending balance: collectively evaluated for impairment $ 403 $ 163 $ 3,444 $ 560 $ 660 $ 24 $ 93 $ 5,347   Gross Loans Receivable (1) :  Ending balance $ 151,356 $ 47,073 $ 216,571 $ 37,338 $ 39,673 $ 1,312 $ - $ 493,323  Ending balance: individually evaluated for impairment $ 304 $ 15 $ - $ - $ - $ - $ - $ 319  Ending balance: collectively evaluated for impairment $ 151,052 $ 47,058 $ 216,571 $ 37,338 $ 39,673 $ 1,312 $ - $ 493,004  (1) Gross Loans Receivable does not include allowance for loan losses of $ ( 5,347 ) or deferred loan costs of $ 3,292 .

(2) Includes one- to four-family construction loans. A loan is considered impaired when, based on current information and events, it is probable that the Company will not be able to collect the scheduled payments of principal and interest when due according to the contractual terms of the loan agreement. Factors considered in determining impairment include payment status, collateral value and the probability of collecting scheduled payments when due. Impairment is measured on a loan-by-loan basis for commercial real estate loans and commercial loans. Larger groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Company does not separately identify individual consumer, home equity, or one- to four-family loans for impairment disclosure, unless they are subject to a troubled debt restructuring.  The following is a summary of information pertaining to impaired loans at or for the periods indicated:   Unpaid Average Interest  Recorded Principal Related Recorded Income  Investment Balance Allowance Investment Recognized  For the Nine Months Ended  At September 30, 2020 September 30, 2020  (Dollars in thousands)  With no related allowance recorded:  Residential, one- to four-family $ 304 $ 304 $ - $ 312 $ 11  Home equity 15 15 - 16 -  Total impaired loans 319 319 - 328 11      Unpaid Average Interest  Recorded Principal Related Recorded Income  Investment Balance Allowance Investment Recognized  For the Year Ended  At December 31, 2019 December 31, 2019  (Dollars in thousands)  With no related allowance recorded:  Residential, one- to four-family $ 166 $ 166 $ - $ 173 $ 10  Commercial real estate (1) - - - 27 -  Total impaired loans with no related allowance 166 166 - 200 10   With an allowance recorded:  Commercial real estate (2) - - - 260 8  Commercial loans (3) - - - 31 1  Total impaired loans with an allowance - - - 291 9   Total of impaired loans:  Residential, one- to four-family 166 166 - 173 10  Commercial real estate - - - 287 8  Commercial loans - - - 31 1  Total impaired loans $ 166 $ 166 $ - $ 491 $ 19  (1) This loan was paid off during the year ended December 31, 2019.

(2) Includes $18.6 million of PPP loans which do not require payments for a certain amount of time under the CARES Act and are 100% guaranteed by SBA .  The accrual of interest on loans is discontinued when, in management’s opinion, the borrower may be unable to meet payments as they become due. A loan does not have to be 90 days delinquent in order to be classified as non-accrual. When interest accrual is discontinued, all unpaid accrued interest is reversed. If ultimate collection of principal is in doubt, all cash receipts on impaired loans are applied to reduce the principal balance .  The Company’s policies provide for the classification of loans as follows: · Pass/Performing; · Special Mention – does not currently expose the Company to a sufficient degree of risk but does possess credit deficiencies or potential weaknesses deserving the Company’s close attention; · Substandard – has one or more well-defined weaknesses and are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. A substandard asset would be one inadequately protected by the current net worth and paying capacity of the obligor or pledged collateral, if applicable; · Doubtful – has all the weaknesses inherent in substandard loans with the additional characteristic that the weaknesses present make collection or liquidation in full on the basis of currently existing facts, conditions and values questionable, and there is a high possibility of loss; and · Loss – loan is considered uncollectible and continuance without the establishment of a specific valuation reserve is not warranted.   The Company’s Asset Classification Committee is responsible for monitoring risk ratings and making changes as deemed appropriate. Each commercial loan is individually assigned a loan classification. The Company’s consumer loans, including residential one- to four-family loans and home equity loans, are not classified as described above. Instead, the Company uses the delinquency status as the basis for classifying these loans. Generally, all consumer loans more than 90 days past due are classified and placed in non-accrual. Such loans that are well-secured and in the process of collection will remain in accrual status.  The following tables summarize the internal loan grades applied to the Company’s loan portfolio as of September 30, 2020 and December 31, 2019:    Pass/Performing Special Mention Substandard Doubtful Loss Total  (Dollars in thousands)  September 30, 2020  Real Estate Loans:  Residential, one- to four-family (1) $ 148,727 $ - $ 2,629 $ - $ - $ 151,356  Home equity 46,098 - 975 - - 47,073  Commercial (2) 201,494 14,477 600 - - 216,571  Construction - commercial 37,338 - - - - 37,338  Other Loans:  Commercial (3) 34,340 1,030 4,303 - - 39,673  Consumer 1,311 - 1 - - 1,312  Total $ 469,308 $ 15,507 $ 8,508 $ - $ - $ 493,323     Pass/Performing Special Mention Substandard Doubtful Loss Total  (Dollars in thousands)  December 31, 2019  Real Estate Loans:  Residential, one- to four-family (1) $ 152,115 $ - $ 2,634 $ - $ - $ 154,749  Home equity 44,403 - 847 - - 45,250  Commercial 208,042 2,573 605 - - 211,220  Construction - commercial 32,299 - - - - 32,299  Other Loans:  Commercial 22,295 4,425 - - - 26,720  Consumer 1,295 - 2 - - 1,297  Total $ 460,449 $ 6,998 $ 4,088 $ - $ - $ 471,535  (1) Includes one- to four-family construction loans. (2) The increase in commercial real estate loans classified as “Special Mention” was primarily due to a $13 . 3 million loan relationship with one borrower that is well collateralized and supported by guarantors. (3) Includes $18.6 million of PPP loans which are 100% guaranteed by SBA and are graded as Pass/Performing loans.  TDRs occur when we grant borrowers concessions that we would not otherwise grant but for economic or legal reasons pertaining to the borrower’s financial difficulties. A concession is made when the terms of the loan modification are more favorable than the terms the borrower would have received in the current market under similar financial difficulties. These concessions may include, but are not limited to, modifications of the terms of the debt, the transfer of assets or the issuance of an equity interest by the borrower to satisfy all or part of the debt, or the addition of borrower(s). The Company identifies loans for potential TDRs primarily through direct communication with the borrower and evaluation of the borrower’s financial statements, revenue projections, tax returns, and credit reports. Even if the borrower is not presently in default, management will consider the likelihood that cash flow shortages, adverse economic conditions, and negative trends may result in a payment default in the near future. Generally, we will not return a TDR to accrual status until the borrower has demonstrated the ability to make principal and interest payments under the restructured terms for at least six consecutive months. The Company’s TDRs are impaired loans, which may result in specific allocations and subsequent charge-offs if appropriate.  Some loan modifications classified as TDRs may not ultimately result in full collection of principal and interest, as modified, which may result in potential losses. These potential losses have been factored into our overall estimate of the allowance for loan losses.  The following table summarizes the loans that were classified as TDRs as of the dates indicated:    Non-Accruing Accruing TDRs That Have Defaulted on Modified Terms Year to Date  Number of Loans Recorded Investment Number of Loans Recorded Investment Number of Loans Recorded Investment Number of Loans Recorded Investment  (Dollars in thousands)  At September 30, 2020  Real Estate Loans:  Residential, one- to four-family 8 $ 304 1 $ 20 7 $ 284 - $ -  Home equity 1 15 - - 1 15 - -  Total 9 $ 319 1 $ 20 8 $ 299 - $ -    At December 31, 2019  Real Estate Loans:  Residential, one- to four-family 5 $ 166 1 $ 28 4 $ 138 - $ -  No additional loan commitments were outstanding to these borrowers at September 30, 2020 and December 31, 2019.  The following table details the activity in loans which were first deemed to be TDRs during the nine months ended September 30, 2020.    For the Nine Months Ended September 30, 2020  Number of Loans Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment  (Dollars in thousands)  Real Estate Loans:  Residential, one- to four-family 3 $ 150 $ 150  Home equity 1 16 16  Total 4 $ 166 $ 166  There were no loans restructured and classified as TDRs during the three month period ended September 30, 2020.  There were no loans restructured and classified as TDRs during the three and nine month periods ended September 30, 2019.  Foreclosed real estate consists of property acquired in settlement of loans which is carried at its fair value less estimated selling costs. Write-downs from cost to fair value less estimated selling costs are recorded at the date of acquisition or repossession and are charged to the allowance for loan losses. Foreclosed real estate was $197,000 and $779,000 at September 30, 2020 and December 31, 2019, respectively, and was included as a component of other assets on the consolidated statements of financial condition. The recorded investment of consumer mortgage loans secured by residential real estate properties for which formal foreclosure proceedings are in process according to local requirements of the applicable jurisdiction was $1.6 million and $1.8 million at September 30, 2020 and December 31, 2019, respectively.

A majority of the growth in core deposits during the nine months ended September 30, 2020 was due to organic growth, PPP loan proceeds and other government stimulus funds remaining on deposit at the Bank, and the impact of the COVID-19 pandemic on consumer and business spending and savings levels. The Company’s strategic focus remains on organic growth of lower-cost core deposits among its retail and commercial customers in an effort to manage interest expense and to strengthen customer relationships.

Earnings per Share [Abstract]
Earnings per Share	Note 6 – Earnings per Share Earnings per share was calculated for the three and nine months ended September 30, 2020 and 2019, respectively. Basic earnings per share is based upon the weighted average number of common shares outstanding, exclusive of unearned shares held by the Employee Stock Ownership Plan of Lake Shore Bancorp, Inc. (the “ESOP”), unearned shares held by the Lake Shore Bancorp, Inc. 2006 Recognition and Retention Plan (“RRP”), and unearned shares held by the Lake Shore Bancorp, Inc. 2012 Equity Incentive Plan (“EIP”). Diluted earnings per share is based upon the weighted average number of common shares outstanding and common share equivalents that would arise from the exercise of dilutive securities. Stock options are regarded as potential common stock and are considered in the diluted earnings per share calculations to the extent they would be dilutive and computed using the treasury stock method. The calculated basic and diluted earnings per share are as follows:   Three Months Ended September 30,  2020 2019  Numerator – net income $ 1,231,000 $ 1,212,000  Denominator:  Basic weighted average shares outstanding 5,941,540 5,987,857  Increase in weighted average shares outstanding due to:  Stock options - -  Diluted weighted average shares outstanding (1) 5,941,540 5,987,857   Earnings per share:  Basic $ 0.21 $ 0.20  Diluted $ 0.21 $ 0.20   Nine Months Ended September 30,  2020 2019  Numerator – net income $ 3,315,000 $ 2,915,000  Denominator:  Basic weighted average shares outstanding 5,968,348 6,011,070  Increase in weighted average shares outstanding due to:  Stock options - -  Diluted weighted average shares outstanding (1) 5,968,348 6,011,070   Earnings per share:  Basic $ 0.56 $ 0.48  Diluted $ 0.56 $ 0.48  (1) Stock options to purchase 64,547 shares under the Company’s 2006 Stock Option Plan and 20,000 shares under the EIP at $14.38 for each plan were outstanding during the three and nine month periods ended September 30, 2 0 20 and 2019, respectively, but were not included in the calculation of diluted earnings per share because to do so would have been anti-dilutive.

Commitments to Extend Credit [Abstract]
Commitments to Extend Credit	Note 7 – Commitments to Extend Credit  The Company has commitments to extend credit with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. Such commitments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated statements of financial condition. The Company’s exposure to credit loss is represented by the contractual amount of these commitments. There were no loss reserves associated with these commitments at September 30, 2020 and December 31, 2019. The Company follows the same credit policies in making commitments as it does for on-balance sheet instruments. The following commitments to extend credit were outstanding as of the dates specified:   Contract Amount  September 30, December 31,  2020 2019  (Dollars in thousands)   Commitments to grant loans $ 63,447 $ 26,919  Unfunded commitments under lines of credit 66,735 61,309  Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses. The commitments for lines of credit may expire without being drawn upon. Therefore, the total commitment amounts do not necessarily represent future cash requirements. The amount of collateral obtained, if it is deemed necessary by the Company, is based on management’s credit evaluation of the customer.

Fair Value of Financial Instruments [Abstract]
Fair Value of Financial Instruments	Note 9 - Fair Value of Financial Instruments Management uses its best judgment in estimating the fair value of the Company’s financial instruments; however, there are inherent weaknesses in any estimation technique. Therefore, for substantially all financial instruments, the fair value estimates herein are not necessarily indicative of the amounts the Company could have realized in a sale transaction on the dates indicated. The estimated fair value amounts have been measured as of September 30, 2020 and December 31, 2019 and have not been re-evaluated or updated for purposes of these consolidated financial statements subsequent to those respective dates. The estimated fair values of these financial instruments subsequent to the respective reporting dates may be different than the amounts reported here.  GAAP establishes a fair value hierarchy that prioritizes the inputs to valuation methods used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities measurements (Level 1) and the lowest priority to unobservable input measurements (Level 3). The three levels of the fair value hierarchy are as follows:  Level 1: Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity can access at the measurement date.  Level 2: Inputs other than quoted prices included in Level 1 that are observable for the asset or liability either directly or indirectly.  Level 3: Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities.  An asset’s or liability’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.  The Company’s consolidated statements of financial condition contains investment securities available for sale and derivative instruments that are recorded at fair value on a recurring basis. For financial instruments measured at fair value on a recurring basis, the fair value measurements by level within the fair value hierarchy used at September 30, 2020 and December 31, 2019 were as follows:     Fair Value Measurements at September 30, 2020  Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Other Unobservable Inputs  Fair Value (Level 1) (Level 2) (Level 3)  (Dollars in thousands)  Measured at fair value on a recurring basis:  Securities available for sale:  Debt Securities  U.S. government agencies $ 2,374 $ 2,374 $ - $ -  Municipal bonds 45,873 - 45,873 -  Mortgage-backed securities:  Collateralized mortgage obligations-private label 19 - 19 -  Collateralized mortgage obligations-government sponsored entities 25,750 - 25,750 -  Government National Mortgage Association 140 - 140 -  Federal National Mortgage Association 4,645 - 4,645 -  Federal Home Loan Mortgage Corporation 2,592 - 2,592 -  Asset-backed securities:  Private label 171 - 171 -  Government sponsored entities 34 - 34 -  Total Debt Securities $ 81,598 $ 2,374 $ 79,224 $ -  Equity securities 43 - 43 -  Total Securities Available for Sale $ 81,641 $ 2,374 $ 79,267 $ -  Interest Rate Swap (1) $ (283) $ - $ (283) $ -  (1) Included in Other Liabilities on the consolidated statements of financial condition.

The following is a description of valuation methodologies used for financial assets recorded at fair value on a recurring basis:  · Investment securities available for sale – the fair values are determined by obtaining quoted market prices on nationally recognized securities exchanges (Level 1) or matrix pricing (Level 2), which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted market prices for the specific securities, but rather by relying on the securities’ relationship to other benchmark quoted prices. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution date, market consensus prepayment projections, credit information and the security’ terms and conditions, among other things. Level 2 securities which are fixed income instruments that are not quoted on an exchange, but are traded in active markets, are valued using prices obtained from our custodian, who use third party data service providers .  · Interest Rate Swap – the fair value is based on a discounted cash flow model. The model’s key assumptions include the contractual term of the derivative contract, including the period to maturity, and the use of observable market based inputs, such as interest rates, yield curves, nonperformance risk and implied volatility.  In addition to disclosure of the fair value of assets on a recurring basis, GAAP requires disclosures for assets and liabilities measured at fair value on a non-recurring basis, such as impaired assets and foreclosed real estate. Loans are generally not recorded at fair value on a recurring basis. Periodically, the Company records non-recurring adjustments to the carrying value of loans based on fair value measurements for partial charge-offs of the uncollectible portions of these loans. Non-recurring adjustments also include certain impairment amounts for collateral-dependent loans calculated when establishing the allowance for loan losses. An impaired loan is carried at fair value based on either a recent appraisal less estimated selling costs of underlying collateral or discounted cash flows based on current market conditions.  For assets measured at fair value on a non-recurring basis, the fair value measurements by level within the fair value hierarchy used at September 30, 2020 and December 31, 2019 were as follows:    Fair Value Measurements  Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs Significant Other Unobservable Inputs  Fair Value (Level 1) (Level 2) (Level 3)  (Dollars in thousands)  Measured at fair value on a non-recurring basis:   At September 30, 2020  Foreclosed real estate $ 197 $ - $ - $ 197   At December 31, 2019  Foreclosed real estate $ 170 $ - $ - $ 170  The following table presents additional quantitative information about assets measured at fair value on a non-recurring basis and for which the Company has utilized Level 3 inputs to determine fair value:    Quantitative Information about Level 3 Fair Value Measurements  (Dollars in thousands) Fair Value Estimate Valuation Technique Unobservable Input Range Weighted Average  At September 30, 2020  Foreclosed real estate $ 197 Market valuation of property (1) Direct Disposal Costs (2) 7.00 - 10.00% 9.21%  At December 31, 2019  Foreclosed real estate $ 170 Market valuation of property (1) Direct Disposal Costs (2) 7.00 - 10.00% 9.40%  (1) Fair value is generally determined through independent third-party appraisals of the underlying collateral, which generally includes various Level 3 inputs which are not observable . (2) The fair value basis of foreclosed real estate may be adjusted to reflect management estimates of disposal costs including, but not necessarily limited to, real estate brokerage commissions, legal fees, and delinquent property taxes. At September 30, 2020 and December 31, 2019, foreclosed real estate valued using Level 3 inputs had a carrying amount of $250,000 and $221,000 , respectively. At September 30, 2020 and December 31, 2019, foreclosed real estate valued using Level 3 inputs had valuation allowances of $53,000 and $51,000 , respectively.

Basis of Presentation [Abstract]
Basis of Presentation	The interim consolidated financial statements include the accounts of Lake Shore Bancorp, Inc. (the “Company”, “us”, “our”, or “we”) and Lake Shore Savings Bank (the “Bank”), its wholly owned subsidiary. All intercompany accounts and transactions of the consolidated subsidiary have been eliminated in consolidation.
Basis of Accounting	The interim consolidated financial statements included herein as of September 30, 2020 and for the three and nine months ended September 30, 2020 and 2019 have been prepared by the Company, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission, and therefore, do not include all information or footnotes necessary for a complete presentation of the consolidated statements of financial condition, results of operations and cash flows in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The consolidated statement of financial condition at December 31, 2019 has been derived from the audited consolidated financial statements at that date, but does not include all of the information and footnotes required by GAAP for complete consolidated financial statements. The consolidated financial statements reflect all adjustments that are, in the opinion of management, necessary for a fair statement of such information and to make the financial statements not misleading. These interim consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. The consolidated statements of income for the three and nine months ended September 30, 2020 are not necessarily indicative of the results for any subsequent period or the entire year ending December 31, 2020.
Use of Estimates	To prepare these consolidated financial statements in conformity with GAAP, management of the Company made a number of estimates and assumptions relating to the reporting of assets and liabilities and the reporting of revenue and expenses. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, securities valuation estimates, evaluation of impairment of securities and income taxes.
Subsequent Events	The Company has evaluated events and transactions occurring subsequent to the statement of financial condition as of September 30, 2020 for items that should potentially be recognized or disclosed in these consolidated financial statements. The evaluation was conducted through the date these consolidated financial statements were issued.

New Accounting Standards [Abstract]
Impact of Adoption of Recent Accounting Standards, Accounting Guidance and Accounting Standards to be Adopted	 Impact of Adoption of Recent Accounting Standards and Accounting Guidance  Under Section 4013 of the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”), which was signed into law on March 27, 2020, financial institutions have the option to temporarily suspend certain requirements under U.S. generally accepted accounting principles related to troubled debt restructurings (“TDRs”) for a limited period of time to account for the effects of COVID-19. This provision allows a financial institution the option to not apply the guidance on accounting for TDRs to loan modifications, such as extensions or deferrals, related to COVID-19 made between March 1, 2020 and the earlier of (i) December 31, 2020 or (ii) 60 days after the end of the COVID-19 national emergency. The relief can only be applied to modifications for borrowers that were not more than 30 days past due as of December 31, 2019. The Company elected to adopt this provision of the CARES Act.  In addition, the Company’s banking regulators and other financial regulators, on March 22, 2020 and revised April 7, 2020, issued a joint interagency statement titled the “Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus” that encourages financial institutions to work prudently with borrowers who are or may be unable to meet their contractual payment obligations due to the effects of the COVID-19 pandemic. Pursuant to the interagency statement, loan modifications that do not meet the conditions of Section 4013 of the CARES Act may still qualify as a modification that does not need to be accounted for as a TDR. Specifically, the agencies confirmed with the staff of the Financial Accounting Standards Board (“FASB”) that short-term modifications made in good faith in response to the pandemic to borrowers who were current prior to any relief are not TDRs under GAAP. This includes short-term (e.g. six months) modifications such as payment deferrals, fee waivers, extensions of repayment terms, or delays in payment that are insignificant. Borrowers considered current are those that are less than 30 days past due on their contractual payments at the time a modification program is implemented. Appropriate allowances for loan and lease losses are expected to be maintained. With regard to loans not otherwise reportable as past due, financial institutions are not expected to designate loans with deferrals granted due to the pandemic as past due because of the deferral. The interagency statement also states that during short-term pandemic-related loan modifications, these loans generally should not be reported as nonaccrual. The Company elected to adopt this interagency guidance.  The Company implemented a loan modification program for impacted customers, in line with regulatory guidance, allowing customers to defer loan payments. The majority of loan deferrals were granted for deferral of principal and interest payments for 90 days, and up to 180 days in some instances, with the loan repayment period extended by the deferral period. The requests are evaluated individually and approved modifications are based on the unique circumstances of each borrower. During the second quarter of 2020, the Company approved loan payment deferral requests of up to 90 days on 219 loans, representing $103.1 million, or 21.1% , of the Bank’s loan portfolio as of June 30, 2020. 88.2% of the loan balances with payment deferrals were for commercial real estate loans and commercial business loans, while the remaining 11.8% were for residential mortgage, home equity and consumer loans. The number of loan payment deferral requests has decreased and as of October 31, 2020 , there were 25 loans, representing $20.8 million, or 4.1% of the Bank’s loan portfolio, that are deferring payments, as follows:     Loan Type Number of Loans Balance Outstanding Weighted Average Interest Rate   Commercial real estate 16 $ 17,608 5.06 %  Commercial business 9 3,165 5.02  25 $ 20,773 5.05 % These loans were current at the time of modification and were not considered troubled debt restructurings based on the CARES Act and interagency guidance noted above and we have not accounted for the loans as TDRs, nor have we designated the loans as past due or non-accrual.  The adoption of these provisions under Section 4013 of the CARES Act and interagency guidance may have a material impact on the Company’s consolidated financial statements; however, the Company cannot quantify the impact at this time.  Accounting Standards to be Adopted  In June 2016, the FASB issued Accounting Standard Update (“ASU”) 2016-13, “ Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments ” (“ASU 2016-13”). ASU 2016-13 requires credit losses on most financial assets measured at amortized cost and certain other instruments to be measured using an expected credit loss model (referred to as the current expected credit loss (“CECL”) model). Under the CECL model entities will estimate credit losses over the entire contractual term of the instrument (considering estimated prepayments, but not expected extensions or modifications unless reasonable expectation of a troubled debt restructuring exists) from the date of initial recognition of that instrument. Further, ASU 2016-13 made certain targeted amendments to the existing impairment standards for available for sale (“AFS”) debt securities. For an AFS debt security for which there is neither the intent nor a more-likely-than-not requirement to sell, an entity will record credit losses as an allowance rather than a write-down of the amortized cost basis. An entity will apply the amendments in ASU 2016-13 through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective.  The Company has determined its data requirements and is developing its methodologies for calculating the expected credit losses under ASU 2016-13 which has allowed the Company to run parallel loss reserve calculations. Data integrity associated with these methodologies is being reviewed and enhancements to the current process are being considered. We expect that the new guidance will result in an increase to the allowance for loan losses given that the allowance will be required to cover the full remaining expected life of the portfolio, rather than the incurred loss under the current accounting standard. The extent of this increase is still being evaluated. We are also reviewing the impact of additional disclosures required under ASU 2016-13 on our ongoing financial reporting procedures.  ASU 2016-13 was originally effective for the Company in 2020. In November 2019, the FASB issued guidance to defer the effective date for smaller reporting companies such as the Company until January 1, 2023.

Allowance for Loan Losses (Poli

Allowance for Loan Losses [Abstract]
Allowance for Loan Losses	Management segregates the loan portfolio into loan types and analyzes the risk level for each loan type when determining its allowance for loan losses. The loan types are as follows:  Real Estate Loans: · One- to Four-Family – are loans secured by first lien collateral on residential real estate primarily held in the Western New York region. These loans can be affected by economic conditions and the value of underlying properties. Western New York’s housing market has consistently demonstrated stability in home prices despite economic conditions. Furthermore, the Company has conservative underwriting standards and its residential lending policies and procedures ensure that its one- to four-family residential mortgage loans generally conform to secondary market guidelines. · Home Equity - are loans or lines of credit secured by first or second liens on owner-occupied residential real estate primarily held in the Western New York region. These loans can also be affected by economic conditions and the values of underlying properties. Home equity loans may have increased risk of loss if the Company does not hold the first mortgage resulting in the Company being in a secondary position in the event of collateral liquidation. The Company does not originate interest only home equity loans. · Commercial Real Estate – are loans used to finance the purchase of real property, which generally consists of developed real estate that is held as first lien collateral for the loan. These loans are secured by real estate properties that are primarily held in the Western New York region. Commercial real estate lending involves additional risks compared with one- to four-family residential lending, because payments on loans secured by commercial real estate properties are often dependent on the successful operation or management of the properties, and/or the collateral value of the commercial real estate securing the loan, and repayment of such loans may be subject to adverse conditions in the real estate market or economic conditions to a greater extent than one- to four-family residential mortgage loans. Also, commercial real estate loans typically involve relatively large loan balances concentrated with single borrowers or groups of related borrowers. · Construction – are loans to finance the construction of either one- to four-family owner occupied homes or commercial real estate. At the end of the construction period, the loan automatically converts to either a one- to four-family or commercial mortgage, as applicable. Risk of loss on a construction loan depends largely upon the accuracy of the initial estimate of the value of the property at completion compared to the actual cost of construction. The Company limits its risk during construction as disbursements are not made until the required work for each advance has been completed and an updated lien search is performed. The completion of the construction progress is verified by a Company loan officer or inspections performed by an independent appraisal firm. Construction loans also expose us to the risk of construction delays which may impair the borrower’s ability to repay the loan.  Other Loans: · Commercial – includes business installment loans, lines of credit, and other commercial loans. Most of our commercial loans have fixed interest rates, and are for terms generally not in excess of 5 years. Whenever possible, we collateralize these loans with a lien on business assets and equipment and require the personal guarantees from principals of the borrower. Commercial loans generally involve a higher degree of credit risk, as commercial loans can involve relatively large loan balances to a single borrower or groups of related borrowers, with the repayment of such loans typically dependent on the successful operation of the commercial business and the income stream of the borrower. Such risks can be significantly affected by economic conditions. Although commercial loans may be collateralized by equipment or other business assets, the liquidation of collateral in the event of a borrower default may be an insufficient source of repayment because the equipment or other business assets may be obsolete or of limited use, among other things. Accordingly, the repayment of a commercial loan depends primarily on the credit worthiness of the borrowers (and any guarantors), while liquidation of collateral is a secondary and often insufficient source of repayment. · Consumer – consist of loans secured by collateral such as an automobile or a deposit account, unsecured loans and lines of credit. Consumer loans tend to have a higher credit risk due to the loans being either unsecured or secured by rapidly depreciable assets. Furthermore, consumer loan payments are dependent on the borrower’s continuing financial stability, and therefore are more likely to be adversely affected by job loss, divorce, illness or personal bankruptcy.  The allowance for loan losses is a valuation account that reflects the Company’s evaluation of the losses inherent in its loan portfolio. In order to determine the adequacy of the allowance for loan losses, the Company estimates losses by loan type using historical loss factors, as well as other environmental factors, such as trends in loan volume and loan type, loan concentrations, changes in the experience, ability and depth of the Company’s lending management, and national and local economic conditions. The Company's determination as to the classification of loans and the amount of loss allowances are subject to review by bank regulators, which can require the establishment of additional loss allowances.  The Company also reviews all loans on which the collectability of principal may not be reasonably assured, by reviewing payment status, financial conditions and estimated value of loan collateral. These loans are assigned an internal loan grade, and the Company assigns an amount of loss allowances to these classified loans based on loan grade.  Although the allocations noted below are by loan type, the allowance for loan losses is general in nature and is available to offset losses from any loan in the Company’s portfolio. The unallocated component of the allowance for loan losses reflects the margin of imprecision inherent in the underlying assumptions used in the methodologies for existing specific and general losses in the portfolio.
Impaired Financing Receivable	A loan is considered impaired when, based on current information and events, it is probable that the Company will not be able to collect the scheduled payments of principal and interest when due according to the contractual terms of the loan agreement. Factors considered in determining impairment include payment status, collateral value and the probability of collecting scheduled payments when due. Impairment is measured on a loan-by-loan basis for commercial real estate loans and commercial loans. Larger groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Company does not separately identify individual consumer, home equity, or one- to four-family loans for impairment disclosure, unless they are subject to a troubled debt restructuring.
Nonaccrual Loan Status	 The accrual of interest on loans is discontinued when, in management’s opinion, the borrower may be unable to meet payments as they become due. A loan does not have to be 90 days delinquent in order to be classified as non-accrual. When interest accrual is discontinued, all unpaid accrued interest is reversed. If ultimate collection of principal is in doubt, all cash receipts on impaired loans are applied to reduce the principal balance .
Financing Receivable Credit Quality	 The Company’s policies provide for the classification of loans as follows: · Pass/Performing; · Special Mention – does not currently expose the Company to a sufficient degree of risk but does possess credit deficiencies or potential weaknesses deserving the Company’s close attention; · Substandard – has one or more well-defined weaknesses and are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. A substandard asset would be one inadequately protected by the current net worth and paying capacity of the obligor or pledged collateral, if applicable; · Doubtful – has all the weaknesses inherent in substandard loans with the additional characteristic that the weaknesses present make collection or liquidation in full on the basis of currently existing facts, conditions and values questionable, and there is a high possibility of loss; and · Loss – loan is considered uncollectible and continuance without the establishment of a specific valuation reserve is not warranted.   The Company’s Asset Classification Committee is responsible for monitoring risk ratings and making changes as deemed appropriate. Each commercial loan is individually assigned a loan classification. The Company’s consumer loans, including residential one- to four-family loans and home equity loans, are not classified as described above. Instead, the Company uses the delinquency status as the basis for classifying these loans. Generally, all consumer loans more than 90 days past due are classified and placed in non-accrual. Such loans that are well-secured and in the process of collection will remain in accrual status.
Loans and Leases Receivable, Troubled Debt Restructuring	TDRs occur when we grant borrowers concessions that we would not otherwise grant but for economic or legal reasons pertaining to the borrower’s financial difficulties. A concession is made when the terms of the loan modification are more favorable than the terms the borrower would have received in the current market under similar financial difficulties. These concessions may include, but are not limited to, modifications of the terms of the debt, the transfer of assets or the issuance of an equity interest by the borrower to satisfy all or part of the debt, or the addition of borrower(s). The Company identifies loans for potential TDRs primarily through direct communication with the borrower and evaluation of the borrower’s financial statements, revenue projections, tax returns, and credit reports. Even if the borrower is not presently in default, management will consider the likelihood that cash flow shortages, adverse economic conditions, and negative trends may result in a payment default in the near future. Generally, we will not return a TDR to accrual status until the borrower has demonstrated the ability to make principal and interest payments under the restructured terms for at least six consecutive months. The Company’s TDRs are impaired loans, which may result in specific allocations and subsequent charge-offs if appropriate.  Some loan modifications classified as TDRs may not ultimately result in full collection of principal and interest, as modified, which may result in potential losses. These potential losses have been factored into our overall estimate of the allowance for loan losses.
Foreclosed Real Estate	Foreclosed real estate consists of property acquired in settlement of loans which is carried at its fair value less estimated selling costs. Write-downs from cost to fair value less estimated selling costs are recorded at the date of acquisition or repossession and are charged to the allowance for loan losses.

Earnings per Share (Policy)

Earnings per Share [Abstract]
Earnings per Common Share	Earnings per share was calculated for the three and nine months ended September 30, 2020 and 2019, respectively. Basic earnings per share is based upon the weighted average number of common shares outstanding, exclusive of unearned shares held by the Employee Stock Ownership Plan of Lake Shore Bancorp, Inc. (the “ESOP”), unearned shares held by the Lake Shore Bancorp, Inc. 2006 Recognition and Retention Plan (“RRP”), and unearned shares held by the Lake Shore Bancorp, Inc. 2012 Equity Incentive Plan (“EIP”). Diluted earnings per share is based upon the weighted average number of common shares outstanding and common share equivalents that would arise from the exercise of dilutive securities. Stock options are regarded as potential common stock and are considered in the diluted earnings per share calculations to the extent they would be dilutive and computed using the treasury stock method.

Commitments to Extend Credit [Abstract]
Commitments to Extend Credit	Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses. The commitments for lines of credit may expire without being drawn upon. Therefore, the total commitment amounts do not necessarily represent future cash requirements. The amount of collateral obtained, if it is deemed necessary by the Company, is based on management’s credit evaluation of the customer.

Fair Value, Assets and Liabilities Measured on Recurring and Nonrecurring Basis [Line Items]
Fair Value of Financial Instruments	GAAP establishes a fair value hierarchy that prioritizes the inputs to valuation methods used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities measurements (Level 1) and the lowest priority to unobservable input measurements (Level 3). The three levels of the fair value hierarchy are as follows:  Level 1: Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity can access at the measurement date.  Level 2: Inputs other than quoted prices included in Level 1 that are observable for the asset or liability either directly or indirectly.  Level 3: Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities.  An asset’s or liability’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. 
Fair Value, Nonrecurring [Member]
Fair Value, Assets and Liabilities Measured on Recurring and Nonrecurring Basis [Line Items]
Fair Value of Financial Instruments	In addition to disclosure of the fair value of assets on a recurring basis, GAAP requires disclosures for assets and liabilities measured at fair value on a non-recurring basis, such as impaired assets and foreclosed real estate. Loans are generally not recorded at fair value on a recurring basis. Periodically, the Company records non-recurring adjustments to the carrying value of loans based on fair value measurements for partial charge-offs of the uncollectible portions of these loans. Non-recurring adjustments also include certain impairment amounts for collateral-dependent loans calculated when establishing the allowance for loan losses. An impaired loan is carried at fair value based on either a recent appraisal less estimated selling costs of underlying collateral or discounted cash flows based on current market conditions.

Fair Value, Nonrecurring [Member]
Fair Value, Assets and Liabilities Measured on Recurring and Nonrecurring Basis [Line Items]
Fair value measurements valuation technique	Periodically, the Company records non-recurring adjustments to the carrying value of loans based on fair value measurements for partial charge-offs of the uncollectible portions of these loans. Non-recurring adjustments also include certain impairment amounts for collateral-dependent loans calculated when establishing the allowance for loan losses. An impaired loan is carried at fair value based on either a recent appraisal less estimated selling costs of underlying collateral or discounted cash flows based on current market conditions.
Fair Value Inputs Level 1 And Level 2 [Member] | Fair Value, Recurring [Member] | Available-for-sale Securities [Member]
Fair Value, Assets and Liabilities Measured on Recurring and Nonrecurring Basis [Line Items]
Fair value measurements valuation technique	Investment securities available for sale – the fair values are determined by obtaining quoted market prices on nationally recognized securities exchanges (Level 1) or matrix pricing (Level 2), which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted market prices for the specific securities, but rather by relying on the securities' relationship to other benchmark quoted prices. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution date, market consensus prepayment projections, credit information and the security' terms and conditions, among other things. Level 2 securities which are fixed income instruments that are not quoted on an exchange, but are traded in active markets, are valued using prices obtained from our custodian, who use third party data service providers.

Fair value measurements valuation technique	Interest Rate Swap – the fair value is based on a discounted cash flow model. The model's key assumptions include the contractual term of the derivative contract, including the period to maturity, and the use of observable market based inputs, such as interest rates, yield curves, nonperformance risk and implied volatility.
